No one that hasn't touched the calibre software will suffer from the
existing files. Python (which creates those files when stuff is used)
packages now provide compiled bytecode which also saves the users'
power, and I think it's a great feature. The downside is that all the
*.pyc/*.pyo stuff is in many cases already on disk and it was actually
the third hunk in [1] that brought in the change. Look up the bug
report [2] that hunk is referring to, which is relevant in this case.
There were other such updates in the past for me - and I believe I
used some for/rm loop in bash instead of pacman --force. I think top
note in [3] was added at some point, which will both impose further
cleanness in python packaging and confusion on not-very-savant users
in the future. I also agree with pacman in that it should not handle
such cases, because that's what using arch means to me.

Alternatively, you could have informed yourself about what *.pyc/*.pyo
files are and answered your own question.

cheers!
